many charms of boston, which happens to be my hometown, so I'm a little biased here. When we get emotional, we sometimes use words that are less than polite. Case in point, a guy named papi. That's his nickname. His real name is david ortiz. He is the biggest baseball player in boston. And on a public field in fenway, he uttered what is now being called the expletive heard around the world. It was a solemn moment. Boston was coming together. Exhaling communally. &#9834; And every breath we drew &#9834; Reporter: Honoring the victims, saluting the first responders, singing the national anthem. And then, big papi, david ortiz, the designated hitter and first baseman, stepped to the mic for an inspirational message. We prove this jersey rewear today, it doesn't say red sox. It says boston. Reporter: That's when we learned that big papi has a big potty mo . And nobody's going to take it from us. Stay strong. Thank you. Reporter: The crowd of bostonians, a group of people who, let's be honest, know their way around an f-bomb, ate it up. But here's the problem. Not only there were kids in the house. But this ceremony was being aired on cable. Really, really brilliant. Reporter: The fcc has browned on things like bono cursing on the goaden globes on nbc. But not an hour after big papi's slip of the tongue, no less than the fcc tharm, tweeted out, david ortiz spoke from the heart at today's red sox game. The fcc's indecency rules only apply to broadcasters, not cable. It's not clear if this has affected a change of n thinking. Big papi's speech has become a rallying cry in a wounded but still strong city. They're already selling t-shirts. All right selling t-shirts.
